How the 22319-EK model number is decoded
The SKF 22319 EK is a 95×200×67 mm spherical roller bearing with a 1:12 tapered bore — SKF catalogue execution for sleeve mounting on a 95 mm plain shaft, retaining the double-row self-aligning barrel-roller design. On the SKF nameplate, 22319-ek follows the ISO 15 convention: 2 for the spherical roller type, 23 for the dimension series 23 (heavy OD, wide), final digits 19 for the 95 mm bore. Reading the suffix on 22319-ek, the K (or EK/CCK) element changes only the bore — 1:12 taper for sleeve mounting — while the rest of the suffix chain (CC cages with W33 groove) keeps the same internal design, cage and W33 relubrication features as the cylindrical-bore 22319. The 52.5 mm radial section height ((200−95)/2) and 12000 g catalogue mass frame a 95 mm bore bearing rated at 699 kN C — roughly 7.36 kN of dynamic capacity per millimetre of bore before application factors. Mounting on the 1:12 taper is controlled by clearance reduction or measured axial drive-up, never by locknut torque: SKF tables give the target radial-clearance decrease for the 95 mm 22319-ek, checked with feeler gauges before and after drive-up.
Typical equipment & failure modes
Common applications
- rolling-mill pinion and back-up shafts
- large vibrating screens and feeders
- heavy crusher and screen shafts mounted and dismounted with hydraulic nuts
- long through-shafts in conveyors, where a sleeve seat avoids a precision journal
Known failure patterns
- raceway fatigue spalling of the sphered outer raceway after extended service above the catalogue L10 rating
- inner-ring raceway spalling from edge loading when misalignment exceeds the self-aligning recovery range
- sleeve seizure and shaft seat damage from omitting the anti-seize film between withdrawal sleeve and journal before drive-up
- surface distress and smearing when the relubrication interval is exceeded — the W33 groove is only effective if grease actually reaches the roller rows
- smearing on the roller-raceway contact during skid starts below the minimum load
Selection pitfalls — read before you substitute
- Mount the 95 mm bore 22319-ek by induction heating (max 120 °C) or oil injection — driving a bearing of this section home through the rollers brinells both raceways, and the damage only speaks up as vibration hours later.
- The 22300-series series at 95 mm bore (200×67 mm) is the heavy wide-section choice — highest capacity, lowest speed limit; do not substitute a 222 or 230 series in the same bore without re-checking both life and the 3,400 r/min ceiling.
- A loose sleeve after the first weeks of service usually means inadequate initial drive-up; re-checking clearance without dismounting is possible through the 67 mm-wide roller rows with feeler gauges — do not simply tighten the KM nut until vibration stops.
- The adapter sleeve is selected by actual shaft diameter, not by the 95 mm nominal bearing bore: H-sleeve part numbers span a small diameter range, so two different shaft diameters can use the same 22319-ek with different sleeves.
- The 12000 g mass and 67 mm width mean abutment faces must be square to the axis within the bearing's own P0 tolerance; a tilted spacer tilts the outer ring and concentrates load on one roller row of 22319-ek.
- The 699/765 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 22319 EK); sleeve, KM nut and MB washer are separate order numbers, and the catalogue version (SKF catalogue PUB BU/P1 17000) should travel with the mounting specification.
Frequently asked questions
What are the dimensions and catalogue data of 22319-ek?
The SKF 22319 EK is a double-row spherical roller bearing with a 1:12 tapered bore, 95 mm nominal bore, 200 mm outer diameter and 67 mm width (3.74 × 7.874 × 2.638 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: C 699 kN, C0 765 kN, Pu 73.5 kN, reference speed 2,600 r/min, limiting speed 3,400 r/min, mass about 12000 g. It is mounted on an adapter (H) or withdrawal (AH) sleeve, not directly on the shaft.
What does the K suffix mean on 22319-ek?
K marks a 1:12 tapered bore for sleeve mounting — SKF writes EK or CCK(/W33), FAG writes -K- inside the suffix chain for sleeve mounting. The bearing seats on an H-series adapter sleeve with a KM locknut and MB lock washer (plain shaft, h9 tolerance), or on an AH withdrawal sleeve against a shaft shoulder. The rarer K30 suffix would instead mean a 1:30 taper; dimension series 40/41 spherical rollers commonly use it.
Which adapter sleeve fits the 22319-ek?
The sleeve is selected by the actual shaft diameter in millimetres, not only by the 95 mm nominal bore: SKF H-sleeve numbers each cover a small shaft-diameter range and are width-series specific (H39/H30/H31/H32 matching dimension series 39/40/31/32), and each kit bundles the sleeve, KM locknut and MB lock washer. For shoulder locations use an AH withdrawal sleeve instead. Confirm the sleeve number against the SKF catalogue PUB BU/P1 17000 mounting tables for your shaft size.
How is the 22319-ek driven up and checked?
Mounting is controlled by radial-clearance reduction or axial drive-up distance from the SKF catalogue tables for the 1:12 taper, never by locknut torque. Measure clearance with feeler gauges before and after tightening the KM nut, stop at the tabulated decrease, and lock the MB washer tab. Over-drive removes too much clearance (inner-ring cracking risk); under-drive lets the sleeve creep and fret.
What is the difference between 22319-ek and 22319?
They share the ISO 15 envelope and the same 699/765 kN ratings, but 22319-ek has the 1:12 tapered bore for sleeve mounting on a plain shaft, while 22319 has a cylindrical bore for direct mounting on a machined interference journal (typically k5 with H7 housing). They are separate order numbers, not interchangeable in the same shaft arrangement.
